The computer module gathers this information to determine the remaining pad life. Once pads and sensor have been replaced, the brake life service indicator on the dash will need to be reset. Depending on make, model and year, this may be done on the dashboard or with the use of a scan tool. Electronic wear sensors, in addition to pad friction material, are wear-related items. The sensors should be replaced every time the pads are changed, even if the sensor visually looks OK. Regardless of outward appearance, the wire harness and the sensor may have experienced severe thermal cycle duty and can be prone to failure. The sensors are relatively in-
expensive items and should always be replaced whenever the pads are serviced.
The future of brake pads
We asked a number of experts if there have been any recent/impending advancements in brake pad friction material and/or design. Here are some comments.
